DISPENSER FOR LIQUID-soar AND THE LIKE.

Specification of Letters Patent."

Application filed January 31, 1914. Serial No. 815,662. j

To all whom it may concern Be it known that I, EvERE'rr E. BUSSEY,

a citizen-of the United Statesyand a resident of Malden, in the countyof Middlesex and State of Massachusetts, have invented a new and usefulImprovement in Dispensers for Liquid Soap and the like, of which thefollowing is a specification.

My invention relates to dispensers for liquid-soap and the like and morevespecially to devices of this character in which a small charge ofliquid is delivered by the manual actuation of a valve located at thelower portion of the container.

The object of my invention is to-improve and simplify the constructionof containers for liquids in the manner hereinafter set forth.

One embodiment of my invention is shown in the accompanying drawings inwhich- Figure l is a vertical central section of a dispenser for liquidembodying my invention. Fig. 2 -is asection taken on the line 22, andFig. 3 is a section taken on the line'3fi3.

.In the particular drawings selected for more fully disclosing theprinciple ofmy,

' as separate from the reservoir, although it .3. Preferably three willbe obvious that it may be made integral therewith. Any suitable meansmay be employed for attaching the neckto the reservoir, and-in thepresent instance I provide a nut 5 threaded to the neck for com pressingthe rubber gasket 6 between the inner wall of the reservoir and saidnut, a flange 4 integral with the neck being in engagement with theoutside of the reservoir.

same is -a plunger 7 provided with one or more lateral recesses,pockets, orlpassages 8 for conveying a predetermined q'uantity or chargeof' liquid from the reservoir to the delivery chamber or mor'esuchrecesses 7 Located within the neck and having. a

sliding fit with the spire and the top of the are employed, so that theplunger may have three or more points of support on the interior wall 9of the neck. This is desirable Patented Fee, 29, 1916.

because therebywthe plunger is kept in per- 1 feet alinement with thevalve seatwithout unduly prolonging the plunger and Without lengtheningthe neck in which it reciprocates. Unless three or more such points ofsupport are provided, the proper v seating of the valve 11 on itssquared valve seat to close the lower end of the delivery chamber is notalways 12 being often partially open. By means of my construction,however,

always squarely seated, leakage being thereby prevented. The deliverychamber is propossible, such seat-- -ing being at best uncertain theoutlet' the plunger is always positively guided and the valvevided withan outlet 12 through which pro jects the handle 10 of the plunger, arubber gasket 11, which surrounds the'handle just below its'juncturewith the plunger, constituting a valve cooperating with a squaredvalve-seat 11 cut into the lower portion of the chamber 3.

. 17 surrounding a pin l6.which, if employed,

rises from the plunger, said standards 18 constituting means for guidingthe plunger in its-reciprocal movements and the spaces between saidstandards ports through which the contents of the reservoir may flowinto the upper'chamber or-cage formed by the standards the rim and thecap. As shown, the-spring is tapering in longitudinal section, thespires thereof being 'of progressively decream'ng diameter downwardly,so that. when compressed by forcing the plunger up to its full extent,the

spires will benested within the topmost plunger separated The valve seatpreferably isform'ed by counterboring the upper part from the undersideof the cap 15 by the thickness of the wire by which the spring isformed. 'This is advantageous as-it permits the use of a shorter neck.

In devices of this character it is desirable to deliver a' smallquantity or charge of soap at a time in order to prevent waste and it ispreferable to have the delivery chamber air-tight. As will be obvious,the plunger is normally held downward so that the outlet 12 is closed bythe gasket 11.

The upward movement of the plunger is limited as aforesaid only bythethickness of a single spire or coil ofthe spring 17 which surrounds theplunger pin. When the plunger is held on its seat, its upper awayportions 13, 14, and upon the release of the handle, the plunger underthe action of its spring, will be thrust downward and a charge of liquidthereby conveyed bodily from the reservoir to the chamber. The plungeris then again pushed upwardly as before and a second charge flows intothe plunger passage. On the release of the plunger its spring againforces it downward and the liquid charge previously conducted into theair-tight chamber is forced or crowded by the incoming charge out of thechamber-past said valve seat, and expelled through the chamber outlet.around the handle and down along the latter into the palm of the hand.The handle in projecting through the outlet assists in conducting andguiding the liquid directly into the palm of the hand. Thus therepeatedoperation of the handle and its plunger aS described takes"charges from the reservoir and carries them bodily successively into thedelivery cham her. After the first charge has been delivered it will notbe necessary in obtaining the next charge to push the plunger upwardtwice, since a charge will always be in the chamber in readiness to bedelivered therefrom on the first upward push of the plun- Heretofore. inliquid soap dispensers, considerable difficulty has been experiencedfrom the drying and clogging of the delivery mechanism, owing, amongother rea- 1 sons, to the fact that such mechanisms have been exposed tothe air between operations. By my invention the discharging mechanism isnot exposed to the air at any time excepting on the delivery of liquidtherethrough since the mechanism is inclosed in the air-tight chamberand the ingress of air thereto is effectively prevented by these-a1- ingof the outlet end of the chamber by the plunger valve on the valve seat.As shown herein the liquid charge conveyed by the .rectly with thereservoir.

plunger passage 8 is not suilicient to completely fill the chambersurrounding the plunger, but there is a volume of air pocketed above thecharge resting on thebottom of the chamber above its outlet. Thisconstitutes a fluid seal beneath the upper valve portion of the plungerwhich closes the entrance between the reservoir and chamber, andefiectively prevents any leakage of liquid from said reservoir past saidplunger into said chamber. As a result the same volume of liquid chargeis always delivered from the chamber. lVhile herein both liquid and airare in the chamber it will be apparent that the seal would exist ifeither air or liquid were in the chamber. Any tendency to dry or clogthe delivery mechaanism is further prevented by the fact that saidmechanism is continuously surrounded and kept wet by the liquid in thechamber. If there should be at any time an-accu'mulation of dry soapexterior of the Valve seat in the annular discharge openings surroundingthe handle it is automatically dislodged when the handle is movedupwardly for effecting a discharge operation.

It has been found in practice that devices of this. character areliableto leak because the valve on the plunger does not always accuratelycooperate with its valve seat.

such number of passages 8 that the plunger will have at least threepoints of support on the interior of the neck, thereby insuring theaccurate registering of the valve with its seat. It has also been foundthat reservoirs in liquid soap dispensers are liable to breakage due totemperature changes when the wall bracket engages di- Accordingly, inthe present instance, I have provided a bracket 19 having a wall plate20 at one end and a two-part clamp 22, 23, at the other, said clampengaging the neck itself as distinguished from the reservoir, so thatthe contact will be between metal and metal as distinguished from metaland glass, as is the case where the bracket embraces the lower part ofthe reservoir itself. The clamp preferably engages the neck between theflanges 4, 21 and the two halves thereof are united by screws 24threaded into the lugs 25, 26, or in any other suitable manner.

A dispenser such as described above provides a very advantageousconstruction; it is simple in construction and operation, cheap tomanufacture and is not liable to get out of order. Y

While the dispenser has been described herein as applicable forreceiving liquid soap, it will be readily understood that it may be usedfor delivering perfumery or other liquids or materials.
